An asteroseismic age estimate of the open cluster NGC 6866 using Kepler and Gaia
K. Brogaard, T. Arentoft, A. Miglio +10
Asteroseismology of solar-like oscillations in giant stars allow the derivation of their masses and radii. For members of open clusters this allows an age estimate of the cluster w…
Unresolved Rossby and gravity modes in 214 A and F stars showing rotational modulation
Andreea I. Henriksen, Victoria Antoci, Hideyuki Saio +9
Here we report an ensemble study of 214 A- and F-type stars observed by \textit{Kepler}, exhibiting the so-called \textit{hump and spike} periodic signal, explained by Rossby modes…
Pyodine: An open, flexible reduction software for iodine-calibrated precise radial velocities
Paul Heeren, René Tronsgaard, Frank Grundahl +3
For existing and future projects dedicated to measuring precise radial velocities (RVs), we have created an open-source, flexible data reduction software to extract RVs from échell…
Solar-like oscillations in Cephei A as seen through SONG and TESS
E. Knudstrup, M. N. Lund, M. Fredslund Andersen +11
Fundamental stellar parameters such as mass and radius are some of the most important building blocks in astronomy, both when it comes to understanding the star itself and when der…
